1. 1
   Generously season both sides of roast with salt and pepper. Sprinkle top of roast with 1 tablespoon flour and pat onto meat. Shake off excess.

   Heat vegetable oil in a large skillet over medium-high heat. Sear roast until well-browned, 5 to 6 minutes per side. Remove roast from the skillet and set aside.
3. 3
   Reduce heat to medium. Melt butter in the skillet; cook and stir mushrooms in butter until tender, 3 to 4 minutes. Stir in onion; cook until onions are translucent and brown, about 5 minutes. Add garlic; stir until fragrant, about 1 minute.

   Stir in remaining 1 1/2 tablespoons flour; cook and stir for about 1 minute. Add tomato paste and cook for another minute. Slowly add chicken broth while stirring; return to a simmer. Remove the skillet from heat.
